A study using a transcranial photobiomodulation helmet emitting at 1070 nanometers conducted a head-to-head trial comparing helmet-only therapy to whole-body photobiomodulation (660 nm and 850 nm) and found equivalent improvements in cognition scores and digital symbol substitution test performance between the two modalities.

“they did a head-to-head trial against the entire bed which is whole body photobiomodulation which puts out two different frequencies one at 660 and the other at 850 and what they wanted to do was to actually test out objectively to see whether or not you needed to have a helmet or a whole bed tissue radiation”
